Work will be carried out on Battlefield Road, in the county town, from Monday, November 14 to Sunday, November 20 this year.
It is to facilitate the supermarket chain's large new store being built on the edge of Shrewsbury.
The work is being undertaken by contractor HH Construction and will involve:
The construction of a pedestrian crossing adjacent to the new site entrance
Resurfacing of a section of Battlefield Road between Mayfield Close and the Battlefield Road roundabout
New white lining to incorporate the changes to the highway layout as per the Section 278 agreement
To minimise disruption the work will be carried out overnight from 8pm to 5am and during these times Battlefield Road will be closed between Mayfield Close and the Battlefield Roundabout.
Traffic will be diverted via a signed diversion route with access to residential properties and businesses maintained at all times.
Residents and businesses are to be notified and advanced warning signs will be placed on site two weeks prior to the works starting.
Aldi received permission for the new store in March, which will have wider aisles and more tills to reduce congestion currently experienced by shoppers using the store in Arlington Way.
Bosses have said the new branch will retain all 25 jobs, and create 15 new vacancies, generating £1 million in wages annually.
The existing store in Arlington Way has been in place since 1992, but the business has outgrown the site.
The site was previously earmarked for a Miller & Carter steakhouse, Costa drive-through, Premier Inn and shop units.
